I currently have FFCE 21 deployed to about 100 users. We are only using FF to go to certain websites. However, these websites do generate popups that we need to allow. I have tried to disable the popup blocker via the .adm template. It seems to work for a time but then after they have been using it for awhile it will start to block popups. If they close down FF and reopen it the popups are allowed again for a time. Here is a list of what I have set to try to allow all of the popups.
